Plants that are "creepers" grow along the ground, with vertical leaves or shoot systems attached at each node of the horizontal stem. Such plants often lack secondary growth; how, then, do they supply water and nutrients to a growing number of leaves as the plant spreads?
A) They make more efficient use of the primary vasculature in the stem.
B) Even though no new vasculature can be produced, the existing xylem and phloem in the stem can increase in size and transport capacity.
C) Each stem node initiates its own root meristem, bypassing the need for increasing water and nutrient transport within the prostrate stem.
D) Some lateral branches from the prostrate stem become negatively gravitropic and take on root meristem identity.
